[0029] In this embodiment: the inner support assembly 2 includes an abutment member that can contact the inner wall of the cabin at multiple points, a support member that can connect the retaining frame 1 with the abutment member, and a transmission member that can drive the abutment member to approach the inner wall of the cabin, the transmission member includes a support 201 fixedly connected to both ends of the retaining frame 1, a lead screw 202 is movably connected between the supports 201, a transmission block 203 is fixedly connected to the outer side of the lead screw 202, the support member includes a joint 204 fixedly installed in the retaining frame 1, a support arm 205 is movably connected to one side of the joint 204, and the transmission block A support rod 206 is provided between 203 and the support arm 205, and the abutment member includes an abutment block 207 movably connected to one end of the support arm 205, a limit block 208 is fixedly installed on the abutment block 207, a spring 209 is provided in the limit block 208, a positioning pin 210 is provided between the abutment block 207 and the limit block 208, and extension blocks 211 are provided at the front and rear of the spring 209; the support 201 is rotatably connected to the lead screw 202, the lead screw 202 is connected to the transmission block 203 by threads, and the transmission block 203 is connected to the support rod 20 6 is rotatably connected, the joint 204 and the support rod 206 are rotatably connected to the support arm 205, and the abutment block 207 is slidably connected to the extension block 211; the lead screw 202 is installed in the tooling through the support 201, and the support arm 205 connected to the joint 204 at one end cooperates with the frame rod 103 to limit the movable range of the abutment block 207. When the lead screw 202 rotates relative to the support 201, the transmission block 203 will drive the lower end of the support rod 206 to move horizontally under the common limiting action of the lead screw 202 and the support rod 206, thereby The movement of the lower end of the rod 206 drives the support arm 205 to rotate, and the abutment block 207 contacts the inner wall of the cabin and drives other components belonging to the abutment member to move. The limit block 208 installed on the abutment block 207 through the positioning pin 210 can prevent the extension block 211 from falling from the abutment block 207. The spring 209 can push the extension block 211 to slide relative to the abutment block 207 after the abutment block 207 is separated from the frame rod 103, so that the extension block 211 moves to the extension block 211 on another adjacent abutment block 207.

[0030] In this embodiment: the adjustment component 3 includes a buckle cover 301 fixedly connected to one side of the second carrier 102, a counterweight 302 is fixedly installed in the buckle cover 301, a worm wheel 303 is fixedly connected to one end of the lead screw 202, and end seats 304 are fixedly connected to the front and rear sides of the buckle cover 301, a worm 305 is movably connected between the end seats 304, and the front and rear ends of the worm 305 are fixedly connected to knobs 306; the worm wheel 303 is meshedly connected to the worm 305, and the end seat 304 is rotatably connected to the worm 305; The buckle cover 301 provides protection for the components inside it, and the counterweight block 302 can balance the weight of the end seat 304 and the worm 305 to prevent the center of gravity of the tool from shifting. When the worm 305 is rotated by the knob 306, the rotation of the worm 305 will be transmitted to the screw 202 through the worm wheel 303, so that the screw 202 rotates in a fixed direction, and can prevent the screw 202 from reversing due to obstruction after it is rotated into place. The worm 305 is installed in the buckle cover 301 through the end seat 304 and the movable range of the worm 305 is limited.

[0031] Working principle: When the tooling is installed to complete the internal support work for cabin lathe machining, the staff will put the retaining frame 1 into the cabin, and when the knob 306 is turned to make the worm 305 drive the screw 202 to rotate through the worm gear 303, the rotation of the screw 202 will be transmitted to the support arm 205 through the transmission block 203 and the support rod 206, so that the support arm 205 rotates and drives the abutment block 207 and other parts to move toward the inner wall of the cabin. In this process, the extension block 211 will be pushed out under the action of the spring 209. In the process of the abutment block 207 and the extension block 211 approaching the inner wall of the cabin, the position of the retaining frame 1 can be fine-tuned so that the abutment block 207 and the extension block 211 can touch the predetermined position of the inner wall of the cabin. After the abutment block 207, the limit block 208 and the extension block 211 are pressed against the inner wall of the cabin, the internal support work of the cabin is completed; after the processing is completed, the knob 306 is reversed to reset the components.
